DETAILED DESCRIPTION OF THE DISCLOSURE

The foregoing summary, as well as the following detailed description of certain embodiments will be better understood when read in conjunction with the appended drawings. As used herein, an element or step recited in the singular and preceded by the word “a” or “an” should be understood as not necessarily excluding the plural of the elements or steps. Further, references to “one embodiment” are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Moreover, unless explicitly stated to the contrary, embodiments “comprising” or “having” an element or a plurality of elements having a particular condition can include additional elements not having that condition.

In at least one embodiment, a sanitizing system is a portable system for disinfecting surfaces. The sanitizing system includes a wand assembly and a rolling case assembly. The wand assembly includes a UV lamp, such as a 222 nm UV lamp. A cooling manifold is configured to allow air to blow across a bulb of the UV lamp. The wand assembly may also include a two piece reflector, a master power switch, and a trigger switch to illuminate the UV lamp.

In at least one embodiment, the rolling case assembly includes a hard plastic case with a hinged upper lid portion, a lower body portion, two casters, and an extension handle to facilitate carrying and rolling the cart. The lower body portion contains a power supply, one or more batteries (such as three rechargeable batteries), a power cord for powering the power supply, a cooling fan, and a space to store the wand assembly when not in use. The wand assembly and the rolling case assembly are connected with a vent hose that contains power wiring and transmits cooling air from the cooling fan to the wand housing. The upper lid portion contains a fabric cover to secure the vent hose to the upper lid portion for storage.

During use, the rolling case assembly may be placed away from the area being disinfected, thereby allowing the operator to transport only the wand assembly to the area, and facilitating movement and operation in tight or confined spaces. The wand assembly may include a 300 watt, 222 nm UV lamp, optional ranging lights, a cooling manifold running the length of the housing to blow air out across the bulb to cool the bulb, a two piece reflector positioned in the housing on either side of the cooling manifold to direct light waves, mounts to secure the lamp to the housing, a master power switch on the handle to turn on the system, and a trigger switch on the wand handle that illuminates the lamp when depressed. The reflector may be made out of Teflon or an aluminum sheet, which will enable the reflector to provide electromagnetic shielding. The bulb may be attached to the wand housing with wire straps or bands, which may be positioned on top of Teflon tape and dry woven fiberglass that serve as a cushion between the strap and the glass bulb. The housing for the wand assembly may be approximately (such as +/−0.02 inches) 4 inches wide, 20 inches long, and made out of materials such as fiberglass or reinforced plastic.

In at least one embodiment, the lower body portion of the case contains a power supply mounted on an interior portion, rechargeable batteries, a power cord for connecting electrical power to the power supply, a cooling fan with an outlet through the wall of the lower portion of the case to the hose that connects the wand assembly to the rolling case assembly, at least one latch on the exterior of the lid to secure the upper lid to the lower body portion of the case, and a space to store the wand housing inside the lower body portion when not in use. The rolling case assembly is configured such that the batteries provide power to the UV lamp if the power cord is not plugged into a power outlet. If the power cord is plugged into a power outlet, relays switch over to accept electrical power. In addition, the power cord also supplies power to charge the batteries. A vent hose connects the wand assembly to the rolling case assembly. The vent hose blows the air from the cooling fan in the case through the vent hose and through the cooling manifold in the wand housing to cool the lamp. In addition, the vent hose contains the wiring that is routed from the power supply in the case to the wand assembly to provide power to the UV lamp. The rechargeable batteries may be removed from the backpack or case assembly for charging, or may remain in the backpack to charge as a system. The power cord may be stowed inside the case during transit and battery use. The power cord will exit through a semi-circular hole in the lower body portion of the case when the wand is in use.

When the case is in the closed position, the excess vent hose may be coiled on top of the exterior of the upper lid portion, and a nylon or fabric cover that is attached to one side of the lid exterior is pulled over the hose and secured to the other side of the upper lid portion with buckles or other type mechanical fasteners to secure the cover to the upper lid portion. The lower body portion of the case has a semi-circular shaped opening so that the vent house may be placed in the opening when the wand housing is stored in the case to allow the case to fully close. Additionally, the semi-circular hole will also allow intake air to be drawn into the wand cooling fan even if the case is closed during operation.

FIG. 1 illustrates a perspective view of a portable sanitizing system 100 worn by an individual 101, according to an embodiment of the present disclosure. The portable sanitizing system 100 includes a wand assembly 102 coupled to a backpack assembly 104 that is removably secured to the individual through a harness 105. The wand assembly 102 includes a sanitizing head 106 coupled to a handle 108. In at least one embodiment, the sanitizing head 106 is moveably coupled to the handle 108 through a coupler 110.

In at least one other embodiment, the portable sanitizing system 100 may not be worn by the individual 101. For example, the portable sanitizing system 100 may include a case assembly that is configured to be opened and closed. The case assembly may store the wand assembly 102 when not in use. The case assembly may be opened to allow the wand assembly 102 to be removed and operated.

As shown in FIG. 1 , the wand assembly 102 is in a stowed position. In the stowed position, the wand assembly 102 is removably secured to a portion of the backpack assembly 104, such as through one or more tracks, clips, latches, belts, ties, and/or the like.

In at least one other embodiment, the wand assembly 102 is stored within a case assembly in a stowed position. For example, the wand assembly 102 in the stowed position is contained within a closed case assembly. The case assembly may be opened to allow the wand assembly 102 to be removed and deployed.

FIG. 2 illustrates a perspective lateral top view of the wand assembly 102, according to an embodiment of the present disclosure. The sanitizing head 106 couples to the handle 108 through the coupler 110. The sanitizing head 106 includes a shroud 112 having an outer cover 114 that extends from a proximal end 116 to a distal end 118. As described herein, the shroud 112 contains a UV lamp.

Optionally, the wand assembly 102 may include the sanitizing head 106 connected to a fixed handle. Further, the wand assembly 102 may be sized and shaped differently than shown.

A port 120 extends from the proximal end 116. The port 120 couples to a hose 122, which, in turn, couples to the backpack assembly 104 (shown in FIG. 1 ). The hose 122 contains electrical cords, cables, wiring, or the like that couples a power source or supply (such as one or more batteries) within the backpack assembly 104 (shown in FIG. 1 ) to a UV lamp 140 within the shroud 112. Optionally, the electrical cords, cables, wiring, or the like may be outside of the hose 122. In at least one embodiment, the hose 122 also contains an air delivery line, such as an air tube) that fluidly couples an internal chamber of the shroud 112 to an air blower, vacuum generator, air filters, and/or the like within the backpack assembly 104.

The coupler 110 is secured to the outer cover 114 of the shroud 112, such as proximate to the proximal end 116. The coupler 110 may include a securing beam 124 secured to the outer cover 114, such as through one or more fasteners, adhesives, and/or the like. An extension beam 126 outwardly extends from the securing beam 124, thereby spacing the handle 108 from the shroud 112. A bearing assembly 128 extends from the extension beam 126 opposite from the securing beam 124. The bearing assembly 128 includes one or more bearings, tracks, and/or the like, which allow the handle 108 to linearly translate relative to the coupler 110 in the directions of arrows A, and/or pivot about a pivot axle in the directions of arc B. Optionally, the securing beam 124 may include a bearing assembly that allows the sanitizing head 106 to translate in the directions of arrows A, and/or rotate (for example, swivel) in the directions of arc B in addition to, or in place of, the handle 108 being coupled to the bearing assembly 128 (for example, the handle 108 may be fixed to the coupler 110).

In at least one other embodiment, the wand assembly 102 does not include the coupler 110. Instead, the handle 108 may be fixed to the shroud 112, for example.

In at least one embodiment, the handle 108 includes a rod, pole, beam, or the like 130, which may be longer than the shroud 112. Optionally, the rod 130 may be shorter than the shroud 112. One or more grips 132 are secured to the rod 130. The grips 132 are configured to be grasped and held by an individual. The grips 132 may include ergonomic tactile features 134.

Optionally, the wand assembly 102 can be sized and shaped differently than shown. For example, in at least one example, the handle 108 can be fixed in relation to the shroud 112. Further, the handle 108 may not be configured to move relative to itself and/or the shroud 112. For example, the handle 108 and the shroud 112 can be integrally molded and formed as a single unit.

FIG. 3 illustrates a perspective rear view of the wand assembly 102 of FIG. 2 . FIG. 4 illustrates a perspective lateral view of the wand assembly 102 of FIG. 2 . Referring to FIGS. 3 and 4 , the handle 108 may pivotally couple to the coupler 110 through a bearing 136 having a pivot axle 138 that pivotally couples the handle 108 to the coupler 110. The handle 108 may further be configured to linearly translate into and out of the bearing 136. For example, the handle 108 may be configured to telescope in and out. Optionally, or alternatively, in at least one embodiment, the handle 108 may include a telescoping body that allows the handle 108 to outwardly extend and inwardly recede. In at least one other embodiment, the handle 108 may not be configured to move, extend, retract, or the like relative to the shroud 112.

FIG. 5 illustrates a perspective view of the portable sanitizing system 100 in a compact deployed position, according to an embodiment of the present disclosure. The wand assembly 102 is removed from the backpack assembly 104 (as shown in FIG. 1 ) into the compact deployed position, as shown in FIG. 5 . The hose 122 connects the wand assembly 102 to the backpack assembly 104. In the compact deployed position, the sanitizing head 106 is fully retracted in relation to the handle 108.

FIG. 6 illustrates a perspective view of the portable sanitizing system 100 having the sanitizing head 106 in an extended position, according to an embodiment of the present disclosure. In order to extend the sanitizing head 106 relative to the handle 108, the sanitizing head 106 is outwardly slid relative to the handle 108 in the direction of arrow A′ (or the handle 108 is rearwardly slid relative to the sanitizing head 106). As noted, the sanitizing head 106 is able to linearly translate in the direction of arrow A′ relative to the handle 108 via the coupler 110. The outward extension of the sanitizing head 106, as shown in FIG. 6 , allows for the portable sanitizing system 100 to easily reach distant areas. Alternatively, the sanitizing head 106 may not linearly translate relative to the handle 108.

FIG. 7 illustrates a perspective view of the portable sanitizing system 100 having the sanitizing head 106 in an extended position and the handle 108 in an extended position, according to an embodiment of the present disclosure. To reach even further, the handle 108 may be configured to linearly translate, such as through a telescoping portion, to allow the sanitizing head 106 to reach further outwardly. Alternatively, the handle 108 may not be configured to extend and retract.

In at least one embodiment, the handle 108 may include a lock 109. The lock 109 is configured to be selectively operated to secure the handle 108 into a desired extended (or retracted) position.

FIG. 8 illustrates a perspective view of the portable sanitizing system 100 having the sanitizing head 106 rotated in relation to the handle 108, according to an embodiment of the present disclosure. As noted, the sanitizing head 106 is configured to rotate relative to the handle 108 via the coupler 110. Rotating the sanitizing head 106 relative to the handle 108 allows the sanitizing head 106 to be moved to a desired position, and sweep or otherwise reach into areas that would otherwise be difficult to reach if the sanitizing head 106 was rigidly fixed to the handle 108. Alternatively, the sanitizing head 106 may not be rotatable relative to the handle 108.

FIG. 9 illustrates a perspective end view of a UV lamp 140 and a reflector 142 of the sanitizing head 106, according to an embodiment of the present disclosure. The UV lamp 140 and the reflector 142 are secured within the shroud 112 (shown in FIG. 2 , for example) of the sanitizing head 106. In at least one embodiment, the reflector 142 is secured to an underside 141 of the shroud 112, such as through one or more adhesives. As another example, the reflector 142 is an integral part of the shroud 112. For example, the reflector 142 may be or otherwise provide the underside 141 of the shroud 112. The reflector 142 provides a reflective surface 143 (such as formed of Teflon, a mirrored surface, and/or the like) that is configured to outwardly reflect UV light emitted by the UV lamp 140. In at least one example, shroud 112 may be or include a shell formed of fiberglass, and the reflector 142 may be formed of Teflon that provides a 98% reflectivity. In at least one embodiment, the reflector 142 may be a multi-piece reflector.

The reflector 142 may extend along an entire length of the underside 141 of the shroud 112. Optionally, the reflector 142 may extend along less than an entire length of the underside 141 of the shroud 112.

The UV lamp 140 may extend along an entire length (or along substantially the entire length, such as between the ends 116 and 118). The UV lamp 140 is secured to the reflector 142 and/or the shroud 112 through one or more mounts, such as brackets, for example. The UV lamp 140 includes one or more UV light emitters, such as one more bulbs, light emitting elements (such as light emitting diodes), and/or the like. In at least one embodiment, the UV lamp 140 is configured to emit UV light in the far UV spectrum, such as at a wavelength between 200 nm-230 nm. In at least one embodiment, the UV lamp 140 is configured to emit UV light having a wavelength of 222 nm. For example, the UV lamp 140 may be or include a 300 W bulb that is configured to emit UV light having a wavelength of 222 nm. Alternatively, the UV lamp 140 may be configured to emit UV light in other portions of the UV spectrum, such as the UVC spectrum.

As shown, the reflector 142 includes flat, upright side walls 144 connected together through an upper curved wall 146. The upper curved wall 146 may be bowed outwardly away from the UV lamp 140. For example, the upper curved wall 146 may have a parabolic cross-section and/or profile.

It has been found that the straight, linear side walls 144 provide desired reflection and/or focusing of UV light emitted from the UV lamp 140 toward and onto a desired location. Alternatively, the side walls 144 may not be linear and flat.

FIG. 10 illustrates a perspective end view of the UV lamp 140 and a reflector 142 of the sanitizing head, according to an embodiment of the present disclosure. The reflector 142 shown in FIG. 10 is similar to the reflector 142 shown in FIG. 9 , except that the side walls 144 may outwardly cant from the upper curved wall 146.

FIG. 11 illustrates a perspective end view of the UV lamp 140 and the reflector 142 of the sanitizing head, according to an embodiment of the present disclosure. In this embodiment, the side walls 144 may be curved according to the curvature of the upper curved wall 146.

FIG. 12 illustrates a perspective top view of the sanitizing head 106. FIG. 13 illustrates a perspective bottom view of the sanitizing head 106. FIG. 14 illustrates an axial cross-sectional view of the sanitizing head 106 through line 14-14 of FIG. 12 . Referring to FIGS. 12-14 , air 150 is configured to be drawn into the sanitizing head 106 through one or more openings 152 (or simply an open chamber) of the shroud 112. The air 150 is drawn into the sanitizing head 106, such as via a vacuum generator within the backpack assembly 104 (shown in FIG. 1 ). The air 150 is drawn into the shroud 112, and cools the UV lamp 140 as it passes over and around the UV lamp 140. The air 150 passes into the port 120 and into the hose 122, such as within an air tube within the hose 122. The air 150 not only cools the UV lamp 140, but also removes ozone, which may be generated by operation of the UV lamp 140, within the shroud 112. The air 150 may be drawn to an air filter, such as an activated carbon filter, within the backpack assembly 104.

In at least one embodiment, the portable sanitizing system 100 may also include an alternative ozone mitigation system. As an example, the ozone mitigation system may be disposed in the shroud 112 or another portion of the system, and may include an inert gas bath, or a face inert gas system, such as in U.S. Pat. No. 10,232,954.

Referring to FIG. 13 , in particular, a bumper 153 may be secured to an exposed lower circumferential edge 155 of the shroud 112. The bumper 153 may be formed of a resilient material, such as rubber, another elastomeric material, open or closed cell foam, and/or the like. The bumper 153 protects the sanitizing head 106 from damage in case the sanitizing head 106 inadvertently contacts a surface. The bumper 153 also protects the surface from damage.

The openings 152 may be spaced around the lower surface of the shroud 112 such that they do not provide a direct view of the UV lamp 140. For example, the openings 152 may be positioned underneath portions that are spaced apart from the UV lamp 140.

Referring to FIG. 14 , in particular, the sanitizing head 106 may include a cover plate 154 below the UV lamp 140. The cover plate 154 may be formed of glass, for example, and may be configured to filter UV light emitted by the UV lamp 140. The UV lamp 140 may be secured within an interior chamber 156 defined between the reflector 142 and the cover plate 154. In at least one embodiment, the cover plate 154 is or otherwise includes a far UV band pass filter. For example, the cover plate 154 may be a 222 nm band pass filter that filters UV light emitted by the UV lamp 140 to a 222 nm wavelength. As such, UV light that is emitted from the sanitizing head 106 may be emitted at a wavelength of 222 nm.

Referring to FIGS. 13 and 14 , a rim 157 (such as a 0.020″ thick Titanium rim) may connect the cover plate 154 to the shroud 112. The rim 157 may distribute impact loads therethrough and/or therearound.

In at least one embodiment, ranging light emitting diodes (LEDs) 159 may be disposed proximate to ends of the UV lamp 140. The ranging LEDs 159 may be used to determine a desired range to a structure that is to be sanitized, for example. In at least one embodiment, the ranging LEDs 159 may be disposed on or within the rim 157 and/or the cover plate 154. As another example, the sanitizing head 106 may be configured for range guidance, as disclosed in U.S. Provisional Application No. 63/027,869, which was filed May 20, 2020.

FIG. 15 illustrates a perspective end view of the UV lamp 140 secured to a mounting bracket or clamp 160, according to an embodiment of the present disclosure. Each end of the UV lamp 140 may be coupled to mounting bracket or clamp 160, which secures the UV lamp 140 to the shroud 112 (shown in FIGS. 12-14 ). A buffer, such as a thin (for example, 0.040″) sheet of silicon may be disposed between the end of the UV lamp 140 and the bracket 160. Optionally, the UV lamp 140 may be secured to the shroud 112 through brackets or clamps that differ in size and shape than shown. As another example, the UV lamp 140 may be secured to the shroud 112 through adhesives, fasteners, and/or the like.

FIG. 16 illustrates a perspective exploded view of the backpack assembly 104, according to an embodiment of the present disclosure. The backpack assembly 104 includes a front wall 170 that couples to a rear shell 172, a base 174, and a top cap 176. An internal chamber 178 is defined between the front wall 170, the rear shell 172, the base 174, and the top cap 176. One or more batteries 180, such as rechargeable Lithium batteries, are contained within the internal chamber 178. An air generation sub-system 182 is also contained within the internal chamber 178. The air generation sub-system 182 is in fluid communication with an air tube within the hose 122 (shown in FIG. 2 , for example). The air generation sub-system 182 may include an airflow device, such as a vacuum generator, an air blower, and/or the like. The airflow device is configured to generate airflow to cool the UV lamp, draw air from the sanitizing head 106 into the backpack assembly 104 and out through an exhaust, draw or otherwise remove generated ozone away from the shroud 112, and/or the like.

One or more air filters 183, such as carbon filters, are within the backpack assembly 104. The air filters 183 are in communication with the air tube or other such delivery duct or line that routes air through the hose 122 and into the backpack assembly 104. The air filters 183 are configured to filter the air that is drawn into the backpack assembly 104 from the shroud 112. For example, the air filters 183 may be configured to remove, deactivate, or otherwise neutralize ozone.

The batteries 180 and/or a power supply within the backpack assembly 104 provides operating power for the UV lamp 140 of the sanitizing head 106 (shown in FIG. 2 , for example). The top wall 176 may be removably coupled to the front wall 170 and the rear shell 172. The top wall 176 may be removed to provide access to the batteries 180 (such as to remove and/or recharge the batteries), for example. Additional space may be provided within the backpack assembly 104 for storage of supplies, additional batteries, additional components, and/or the like. In at least one embodiment, the front wall 170, the rear shell 172, the base 174, and the top cap 176 may be formed of fiberglass epoxy.

When a structure to be sanitized is found, the individual may position grasp the handle 108 and position the sanitizing head 106 as desired, such as by extending and/or rotating the sanitizing head 106 relative to the handle 108. The individual may then engage an activation button on the handle 108, for example, to activate the UV lamp 140 to emit sanitizing UV light onto the structure. As the UV lamp 140 is activated, air 150 is drawn into the shroud 112 to cool the UV lamp 140, and divert any generated ozone into the backpack assembly 104, where it is filtered by the air filters 183.

The extendable wand assembly 102 allows the sanitizing head 106 to reach distant areas, such as over an entire set of three passenger seats, from a row within an internal cabin of a commercial aircraft.

FIG. 18 illustrates an ultraviolet light spectrum. Referring to FIGS. 1-18 , in at least one embodiment, the sanitizing head 106 is configured to emit sanitizing UV light (through operation of the UV lamp 140) within a far UV spectrum, such as between 200 nm to 230 nm. In at least one embodiment, the sanitizing head 106 emits sanitizing UV light having a wavelength of 222 nm.

FIG. 19 illustrates a perspective view of a portable sanitizing system 100, according to an embodiment of the present disclosure. The portable sanitizing system 100 includes a case assembly 200 that is configured to store the wand assembly 102 (hidden from view in FIG. 19 ) when the case assembly 200 is in a closed position, as shown in FIG. 19 .

The case assembly 200 may be formed of plastic, for example. The case assembly 200 includes a main body 201, such as a shell, lower body portion, or the like. A cover 202, such as a lid, or upper body portion, is moveably coupled to the main body 201. For example, the cover 202 may be coupled to the main body 201 through a hinge that allows the cover 202 to be opened and closed relative to the main body 201.

The main body 201 includes a base 204 connected to a rear wall 206, lateral walls 208, and a top wall 210. The cover 202 is moveably coupled to a first lateral wall 208, such as through a hinge. One or more latches 212 are disposed on a second lateral wall 208, opposite from the first lateral wall 208. The latches 212 are configured to engage one or more reciprocal latch members 213 extending from the cover 202 to secure the cover 202 in the closed position. The latches 212 may be engaged by an individual to disengage the latch members 213 to allow the cover 202 to be pivoted into an open position.

A handle 214 is secured to the case assembly 200. For example, the handle 214 is pivotally secured to a lateral wall 208. The handle 214 is configured to be grasped by an individual so that the portable sanitizing system 100 may be carried. Optionally, the handle 214 may be secured to other portions of the case assembly 200, such as the top wall 210. In at least one embodiment, the handle 214 may be configured to retract into the case assembly 200 into a fully retracted position, and extend out of (for example, telescope out of) the case assembly 200 into a fully extended position.

Casters 216 or other such wheels may be rotatably secured to a portion of the case assembly 200. For example, two casters 216 may be rotatably secured to the base 204 proximate to the rear wall 206. An individual may tilt the case assembly 200 so that the casters 216 contact a floor. In this manner, the individual may roll the portable sanitizing system 100 via the casters 216 (and optionally through a handle in an extended position from the top wall 210). Alternatively, the case assembly 200 may not include the casters 216.

The hose 122 may outwardly extend from the case assembly 200. In the closed position, when the wand assembly 102 is in a stowed position within the case assembly 200, the hose 122 may be coiled over the cover 202. A hose retainer 218 may secure the hose 122 in place on the cover 202. For example, the hose retainer 218 may include a flexible fabric sheet 220 that is secured to a first side 221 of the cover 202, and may removably secured to an opposite second side 222 of the cover 202, such as through one or more fastening members 224, such as hooks and loops, latches, clips, and/or the like. The hose retainer 218 is configured to secure the hose 122 on the cover 202 when the wand assembly 102 is within a storage chamber of the case assembly 200 and the cover 202 is in a closed position. Alternatively, the hose 122 may be contained within a storage chamber of the case assembly 200 when the wand assembly 102 is not in use. That is, the storage chamber may be sized and shaped to also contain the hose 122 when the wand assembly 102 is also within the storage chamber and the cover 202 is in the closed position.

The wand assembly 102 within the case assembly 200 in the closed position is protected from inadvertent engagement, bumping, and the like. That is, by storing the wand assembly 102 within the case assembly 200, which is closed, when the wand assembly 102 is not in use, the portable sanitizing system 100 protects the wand assembly 102 from potential damage, and increases the useful life of the wand assembly 102.

FIG. 20 illustrates a perspective view of the portable sanitizing system 100 having the case assembly 200 in an open position, according to an embodiment of the present disclosure. As shown, the cover 202 is opened via a hinge 226 that pivotally couples the cover 202 to the main body 201.

An internal or storage chamber 228 is defined between the base 204, the lateral walls 208, the rear wall 206, and the top wall 210 (and the cover 202, when closed). Various components of the portable sanitizing system 100 may be stored within the storage chamber 228. For example, the components within the backpack assembly 104, as described with respect to FIG. 16 , may be contained within the storage chamber 228.

For example, when not in use, the wand assembly 102 is contained within the storage chamber 228. Additionally, one or more batteries, such as rechargeable Lithium batteries, may be contained within the storage chamber 228.

An air generation sub-system (such as a cooling fan) may also be contained within the storage chamber 228. The air generation sub-system may be in fluid communication with an air tube within the hose 122. The hose 122 may be removably connected to the air generation sub-system. In at least one embodiment, the hose 122 is configured to be coupled to and uncoupled from the wand assembly 102 and the air generation sub-system. That is, the hose 122 may be removably coupled to the wand assembly 102 and the air generation sub-system.

One or more air filters, such as carbon filters, may also be within the storage chamber 228. The air filters may be in communication with the air tube or other such delivery duct or line that routes air through the hose 122.

FIG. 21 illustrates a perspective view of the portable sanitizing system 100 having the case assembly 200 in the open position, according to an embodiment of the present disclosure. The wand assembly 102 is configured to be stowed in the storage chamber 228. When the wand assembly 102 is to be used, the cover 202 is opened, and a first end 230 of the hose 122 is coupled to the port 120 of the wand assembly 102. In at least one embodiment, the hose 122 is configured to channel cooling air into the wand assembly 102, in order to cool the UV lamp 140 during activation.

A second end 232 of the hose 122 may be connected to a port 234 extending into and through a portion of the main body 201, such as through a portion of the top wall 210. The port 234 connects the hose 122 to an air generation sub-system, such as a cooling fan 236 that is within the storage chamber 228. The cooling fan 236 may be activated to generate cooling air that is delivered to the wand assembly 102 through the hose 122 (such as an air tube within the hose 122, or through an internal passage of the hose 122 itself).

One or more batteries 180 may also be stowed within the storage chamber 228. For example, three batteries 180 may be within the storage chamber 228.

A power supply 238 is also contained within the storage chamber 228. The power supply 238 may be coupled to the wand assembly 102 through a power cord (such as via a plug and receptacle fitting) to provide power to the wand assembly 102. Further, the power supply 238 may be configured to provide power to the batteries 180 (such as to recharge the batteries 180). The batteries 180 may be secured to the wand assembly 102 and provide power to the wand assembly 102, so that the wand assembly 102 may be used without connection to the power supply 238.

The cooling fan 236 couples to the hose 122 via the port 234. The cooling fan 236 may also include a diverter port 237 that couples to an internal portion of the power supply 238. In this manner, cooling air may be delivered to both the hose 122 (and therefore the wand assembly 102), and the power supply 238, thereby providing cooling to both the wand assembly 102 and the power supply 238.

A hole 240 may be formed through a portion of the case assembly 200. For example, a hole 240 may be formed through a portion of the top wall 210 and sized and shaped to allow the hose 122 to pass therethrough. In this manner, the hose 122 may remain connected to the wand assembly 102 even when the wand assembly 102 is contained within the storage chamber 228 and the cover 202 is closed. Other portions of the hose 122 between the first end 230 and the second end 232 may be secured to the cover 202 by the hose retainer 218, as shown and described with respect to FIG. 19 .

As shown, the handle 214 may be secured to the top wall 210 of the main body 201. The handle 214 may be configured to retracted into and extend out of the main body 201. For example, the handle 214 may be a telescoping handle.

The wand assembly 102 is removably secured within the storage chamber 228. For example, the wand assembly 102 may be removably secured within the storage chamber 228 by one or more latches, clips, or via an interference fir with a conforming portion of the case assembly 200.

The power supply 238 may be fixed in position within the storage chamber 228. For example, the power supply 238 may be fixed in the storage chamber 228 by one or more fasteners, adhesives, or the like. Optionally, the power supply 238 may be secured in position by one or more latches, clips, or the like.

The batteries 180 may similarly be fixed position within the storage chamber 228. For example, the batteries 180 may be fixed in the storage chamber 228 by one or more fasteners, adhesives, or the like. Optionally, the batteries 180 may be secured in position by one or more latches, clips, or the like. In at least one other embodiment, the batteries 180 may be removable, and configured to couple directly to the wand assembly 102 to provide power thereto.

FIG. 22 illustrates a perspective view of the portable sanitizing system 100 having the case assembly 200 in the open position, according to an embodiment of the present disclosure. A power cord 250 may also be stowed within the storage chamber 228. The power cord 250 is contained within the case assembly 200 when the cover 202 is closed and the portable sanitizing system 100 is moved when the wand assembly 102 is not being operated.

Optionally, the power cord 250 connects the power supply 238 to a source of power (such as a wall outlet). In addition to supply air to the wand assembly 102, the hose 122 also routes electrical cables and the like to the wand assembly 102 from the power supply 238 and the batteries 180.

Optionally, the hose 122 may not include electrical connections to the wand assembly 102. Instead, the wand assembly 102, the power cord 250 may plug into the wand assembly 102, via the plug 252, to supply power from the power supply 238 and/or the batteries 180. In this embodiment, as the wand assembly 102 is operated, the plug 252 of the power cord 250 is connected to a reciprocal receptacle of the wand assembly 102. An opposite end of the power cord 250 is connected to the power supply 238 (and/or, a battery 180). The power cord 250 extends out of the case assembly 200 through the hole 240. Thus, the wand assembly 102 may be removed from the storage chamber 228 and connected to the hose 122 and the power cord 250, which extend through the hole 240. The cover 202 may then be closed, thereby securely retaining the power supply 238, the batteries 180, and the like within the storage chamber 228. The wand assembly 102 may then be activated, as it is powered via the power supply 238 or one or more of the batteries 180, and the closed case assembly 200 may be moved, such as via an individual grasping the handle 214 and rolling the case assembly 200 via the casters 216 (shown in FIGS. 19 and 20 ).

Further, the hole 240 also allows intake air to be drawn into the storage chamber 228, even when the cover 202 is closed over the main body 201. Accordingly, the cooling fan 236 is able to receive fresh air, even when the cover 202 is closed.

The power supply 238 may be configured to receive power from a standard power supply, such as a source of alternating current power. For example, the power supply 238 may connect to the source of alternating current power through a power cord. The power cord 250 connects to the wand assembly 252, and is configured to deliver power to the wand assembly 102 to operate the UV lamp 140 from power received from the power supply 238 and optionally the batteries 180. For example, when the power supply 238 is connected to a source of alternating current power, the wand assembly 102 is powered by the power supply 238. In the absence of such power, the wand assembly 102 may be powered by the batteries 180. For example, the wand assembly 102 receives power from the batteries 180 the power supply 238 is not plugged into a power outlet. If the power supply 238 is plugged into a power outlet, one or more relays in the power supply 238 switch over from the batteries 180 to alternating current power supply from the power outlet.

FIG. 23 illustrates a perspective lateral view of the wand assembly 102, according to an embodiment of the present disclosure. As shown, the handle 108 may be fixed in relation to the shroud 112. For example, the handle 108 may be integrally molded and formed with the shroud 112. The wand assembly 102 may be small and compact in order to fit in confined spaced, such as within a flight deck of an aircraft.

An activation trigger 260 is moveably coupled to the handle 108. For example, the activation trigger 260 may be secured to an underside 262 of a main beam 264 of the handle 108. The activation trigger 260 is configured to be selectively pressed and/or depressed to activate and deactivate the UV lamp 140 of the wand assembly 102, as desired.

The activation trigger 260 may be located anywhere along the length of the handle 108. The activation trigger 260 may be shaped differently than shown. Further, the activation trigger 260 may be smaller or larger than shown. As an example, the activation trigger 260 may be a circular button, instead of an elongated bar or beam, as shown. Also, optionally, the activation trigger 260 may be located on a top portion of the main beam 264, or on an extension beam 266, which spaces the handle 108 from the shroud 112. As another example, the activation trigger 260 may be located on a portion of the shroud 112.
